Title: Cutting device
Inventor: IWASAKA HIROYUKI
IPC: B23D15/12
Filed: 1997-04-07
Abstract: PROBLEM TO BE SOLVED: To enable it to cut a workpiece at a desired position without adding an necessary load to the workpiece by enlarging any displacement produced by impressing voltage to an electrostrictive element with an actuator, transmitting it to a cutting edge, and cutting off the workpiece with this cutting edge. SOLUTION: When voltage is impressed on each of piezoelectric elements 19b and 29b with a controller, these piezoelectric element 19b and 29b are extended. Therefore, each one side end of four actuators 11a, 11b, 21a and 21b is pressed, and these actuators 11a, 11b, 21a and 21b are rotated respectively with four uncut parts 17a, 17b, 27a and 27b as the fulcrum each. Accordingly, displacement is enlarged through the principle of leverage, and thereby both ends of two cutting edges 14 and 24 are shifted each, and thus a work material is cut through a double-side cutting-off tool.

Title: Program generating device
Inventor: HATAKI TADASHI
IPC: G06F9/06
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To shorten compilation time by omitting a code development processing about a POU(program organizing unit) which is not changed in the second compilation and afterwards. SOLUTION: A data instance allocation information table generated a memory allocation processing part 64 is stored in the first compilation. When no change of the POU is detected by a POU change judging part 63, memory allocation of a variable of the instance to refer to the POU by the memory allocation processing part 64 is omitted in the second compilation and afterwards. When the POU is not changed and an address of the variable is the same as the one in the preceding time, code generation by a program code development processing part 66 to be continuously performed is omitted by a necessity of development processing judging part 65. Thus, a memory address in the preceding time is preferentially allocated to the variable of the instance to refer to the unchanged POU and the compilation time is shortened by omitting the code generation.

IPC: H01L23/544
Filed: 1981-06-10
Abstract: PURPOSE:To draw the pattern by electron rays accurately while correcting the positions of drawing in blocks on the basis of the results of the detection of marks by dividing a large number of chips mounted onto a substrate into the blocks and forming the marks at every block. CONSTITUTION:A large number of the chips 2 are attached into a semiconductor wafer 1, and these chips 2 are divided into a plurality of the blocks 3 while the marks for detecting the positions are formed at every each block. When drawing the desired block, the position of the mark shaped to the block is detected, and the pattern is drawn by the electron rays while correcting the positions of the drawing of the chips in the block on the basis of the result of the detection. Accordingly, memory capacitance can largely be reduced because the same fields of the chips in the blocks are drawn continuously, and the accuracy of drawing is sharply improved because the positions can be corrected at block units.

Title: Method for controlling strip temperature in radiant tube type continuous heat treatment furnace
IPC: C21D11/00
Filed: 1992-03-13
Abstract: PURPOSE:To control strip temp. with high accuracy and to stabilize the material by changing fluel flow rate in a radiant tube according to change of a strip thickness and a line speed of a metal strip and restraining change of a strip temp. within a range of permissible limit. CONSTITUTION:At the time of changing the strip thickness and/or the line speed of the metal strip, the strip temp. deviation is calculated from the predicted strip temp. based on the equations I, II and III. Further, the fuel flow rate in the radiant tube corresponding to this strip temp. deviation is calculated, and the rate of fluel supplied to the radiant tube is increased by the calculated result under the condition that the change of the predicted strip temp. has a tendency of lowering the strip temp. and decreased under the condition contrary to the above. Further, by beforehand measuring the time constant of change of the furnace temp., the start timing of increasing/decreasing the fluel flow rate is adjusted so as to start before the time of changing the strip temp. and/or the line speed so that the actual strip temp. change is controlled within the range of permissible limit of the previously decided strip temp. change. By this method, for the change in furnace operational conditions, the strip temp. can be controlled with the high accuracy.

Abstract: PURPOSE: To obtain an efficient pump for the circulation of transformer oil and others at the time of intermission and operation by constructing blade faces of a runner to be turned in parallel with a shaft for intermission and in an angle to obtain a desired capacity for operation.  
     CONSTITUTION: When a pump 13 is stopped, a natural circulation of transformer oil is generated by convection flowing from the lower part of a radiator 11 through a casing 14 into the lower part of a transformer 10, pushing each blade 21 of a runner 17 by its flow-pressure. Each blade 21 is turned around the extension l of a holding shaft 22, and a blade face 28 is made in parallel with a shaft 19 to be in parallel with the flow of the natural circulation. Consequently, the flow-line resistance in the casing 14 by the runner 17 is greatly reduced. Meanwhile, when the pump is operated to rotate the runner 17, each blade 21 is brought in contact with a stopper 23 to provide the blade face 28 with a fixed angle to the shaft 19, and the pump is prevented from the lowering of its efficiency.

Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to built-in a thermal shut-off circuit in a CMOS integrated circuit and to perform high-precision thermal shut-off by constituting the thermal shut-off circuit, combining a CMOS transistor with a bipolar transistor formable in a CMOS transistor manufacturing process. SOLUTION: A thermal shut-off circuit outputs from its output terminal 29 a voltage approximately equal to a positive supply voltage as a thermal shut-off signal meaning not being in the state of thermal shut-off, since a third transistor 3 becomes nonconductive at a temperature lower than a set thermal shut-off temperature. On the other hand, a specified negative voltage approximately equal to a negative supply voltage is outputted from the output terminal 29 as a thermal shut-off on signal, since the third transistor 3 becomes conductive if an ambient temperature exceeds a set thermal shut-off temperature. Accordingly, it becomes possible to set a thermal shut-off temperature with a high precision, since it is possible to set a resistance and an emitter area ratio precisely by an integrated circuit manufacturing process.
